lNGOT-MANIPULATOR.

SPECIFICATION forming part of Letters Patent No. 578,415, dated March 9, 1897.

Application filed April 20, 1895. Serial No. 546,527. (No model.)

To all whmn it may concern-.-

Be it known that I, GEORGE W. MCCLURE, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Ingot-Manipulators, of which thefollowing is a full, clear,

and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a side elevation, partly in section, of my improved ingot-n1anipulator; and Fig. 2 is a transverse section of the same.

My invention relates to that class of ma-. nipulators wherein finger-bars are arranged to move between the feed-rolls and push or turn the ingot into position for the various passes of the rolls; and it consists in improved means for operating said finger-bars, as hereand rest upon rollers 8. These rollers are pivoted in the ends of counterweighted levers 9, secured to transverse shafts l0, andto the outer end of each shaft is secured a lever 11, which is pivotally connected by means of a link 12 with a lug 13 upon avertically-movable motive cylinder 14, located at one side of the pit. The stationary plunger 14 of this cylinder is secured to the bed of the pit, as

shown, and is provided with a longitudinal,

port 15, connected to the fluid-supply. To move the truck 4 laterally, I provide two horizontal single-acting cylinders. 16 in line with each other, whose plungers are connected by a common yoke 17, which surrounds the central finger-bar and is provided with antifriction-rollers 18, arranged to make contact with either edge of the finger-bar.

To guide the beams and track supported thereon and insure their moving in a vertical plane, as well as to brace them against canting by the metal operated upon when the truck is at one side of the center, I provide rollers 19 at the ends of the rails 5, which rollers move upon plates 20,,secured to the sides of the frame and. rotating thereon as the manipulator reciprocates vertically.

The operation is apparent, the finger-bars being raised or lowered by the cylinder 14, while their truck is moved laterally by the motive cylinders 16. 1

It is desirable that the finger-bars should be made separate from the truck and fixed thereto by bolts or otherwise, so that they can be replaced if broken.

The advantages of the invention result from the peculiar connection of the motive power for raising and lowering the finger-bars, the canting of 'the plunger and motive cylinder being impossible, as well as from the simplicity and cheapness of the device and the perfoot control of the parts.

Many variations in the form and arrangement of the parts may be made by those skilledin the art without departure from my invention, since What I claim is+ 1. A11 ingot-manipulator comprising oppopositely-extending lever-arms, rollers mounted in stationary bearings upon said arms, a finger-bar platform resting directly upon and carried by said rollers, and means for swinging the lever-arms.

2. An ingot-manipulator comprising oppositely-extending lever-arms, rollers mounted in stationary bearings upon said aru1s,a platform resting directly upon and carried by said rollers, a truck movable upon the platform and carrying the finger-bars, and means. for swinging the lever-arms.

3. In an ingot-manipulator,a movable truck carrying finger-bars, and a motive cylinder having actuating connections with a yoke taking about a fin ger-bar, substantially as described.

4- In aningot-manipulator,a movable truck carrying finger-bars, and a motive cylinder having actuating connections with a yoke taking about a finger-bar, said yoke having antifriction-rollers pivoted therein; substantially as described.

' 5. In an ingot-manipulator,a movable truck carrying finger-bars, and two motive cylinders in line with each other and having their plungers connected to a common yoke taking about a finger-bar; substantially as described.

6. In an ingot-manipulator,a truck carrying the finger-bars and movable upon a platform, links connecting its movable element to le- 10 pivoted levers having rollers upon which said vers upon the shafts of said arms; substanplatform rests, and rollers pivoted in the tially as described.
